The National Transportation Safety Board(NTSB) determined the following probable cause: “The failure of the captain (Malburn McBroom) to monitor properly the aircraft’s fuel state and the crewmember’s advisories regarding the fuel state. This resulted in fuel exhaustion to all engines. The pilots inattention resulted from preoccupation with a landing gear malfunction and the preparations for a possible landing emergency”.

The International Rose Test Garden is a rosegarden in Washington Park in Portland, Oregon. There are over 7,000 rose plants of approximately 550 varieties. The roses bloom from April through October.

In 1917 a group of Portland nurserymen came up with the idea for a rose test garden. Portland had a group of volunteers and 20 miles of rose bordered streets left from the 1905 Lewis & Clark Exposition, and was already dubbed "The City of Roses". Between Portland Parks & Recreationand the American Rose Society, the garden idea soon became a reality.
